The graph below shows a line of best fit for data relating the number of marbles added in a jar to the total weight of the jar, in grams. The line of best fit used to model the data is y = 4.95x + 160.03. Which statement is true for the above graph?

A.
The y-intercept of the line means that the weight of the empty jar is about 160 grams.
B.
The slope of the line means that, on average, for every 1 gram increase in the weight of the jar, approximately 5 marbles are added to it.
C.
The slope of the line means that, on average, for every 1 marble added to the jar, the weight of the jar increases by approximately 8 grams.
D.
The y-intercept of the line means that, initially, there were about 160 marbles in the jar.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
